Protector mechanism for looms

The other end of the spring is preferably straight as shownat 3| and is adapted. for insertion within a selected opening k32,formed in a flange 33 formed upon a" collar Arranged upon the outersides of the ,swordsA II and extending to the front side of the lay aredaggers 31, rigidly secured tothe protector-rod sections IQ. Thesedaggers are adapted toengage with sliding frogs 38.

sleeve 2| will pass the end I 9 of the end protector-rod section I 6 tothe left. This is rendered These frogs may be A employed to actuate thekick-off leverV or brake f devices or both. The frogs 38may be of thetyp shown in Patent 1,322,605. y In the operation of the loom,l the layI.0.,is

`moved back and forth "in theusual manner andv the shuttletravelslongitudinally of the lay and enters the shuttleiboxes at theends of its stroke.

When the shuttle enters either shuttle box thel laywill start on itsforward stroke and complete the forward stroke.V The shuttle willthenhold thebinder I4 in the outer position and the nger 26 will be pressedoutwardlyand theiprotectorrod I5 will be turned in opposition to itsspring 21, whereby both daggers 31 will beY raised sothat they will notengage the sliding frogs. However, should the yshuttle not enter eithershuttle box,

lthe'binder would then not move outwardly and` the `iingerZE wouldremain in theinner position dueto the turning movement of. the bindershaft I5"caused by thespring 21 and the daggers 31 would, remain loweredand. would engage the sliding frogs 38 which would stop theaction vofth`e1ay.' Y Q v` ,It frequently happens that theprotector-rod breaks orbecomes injured whereby the same must beremoved for replacement orrepair. An irnportant feature of the presentinvention is the formingofthe protector-rod in the outer endl protector-rod sections vand theintermediate protector-rod section. rIf either `end protector-rodsection isbroken lor damaged, the set screws' 22 and V23 ar'eloosenedand the adjacent sleeve 2| is slid-backfupon the intermediatelprotector-rod section I1 thus disconnecting the coupling-sleeve 2| fromthe end protector-rod` section IB.V Then the .bearing I 8 is removedfrom thev vsword by un-A screwing the single bolt I8 and this permitsof. the'r'el'noval of the `end protector-rod section I6 withoutdisturbingV the other lgend protector-rod section I6 or theintermediate.protector-rod sectionI1.. It is obvious that either endprotectorrod-.section may` be removedrin this manner, re-

plaoed, and again rigidly connected with the intermediate protector-rodsection-I1.- Should the intermediate protector-rod. .section i right sothat its left end is further spaced from' they inner end I9 of the' end;'protector-rod section, ISto the left and the'.v intermediateprotector-.rodsection |,1` is Lnow angularly adjusted so that its leftfree "end"4 and the *left` coupling- ."iil

vpossible by the fact that there is considerable clearance between lthewalls ofthe bearing 30 and the protector-rod section I1 and there isalso considerable clearance between the wall of the coupling-sleeve 2|and the protector-rod seclerally from its-position. Further, if itshould be desired to remove or replace the spring .21 it will not benecessary to remove the intermediate protector-rod. section I1 or theend protector-rod sections I6. To accomplish this the set screws 22 and23 of the coupling sleeve 2| to the right are.unscrewed and the couplingsleevel 2| to the rightis then slid inwardly upon the intermediateprotector-rod section I1.L The right end of the protector-rods'ection I1is now shifted laterally so that the coupling-sleeve 2| will clear theadjacent 'right end protector-rod section IS `and maybe slid off oftheright endv of thev intermediate protector-rod section I1. The collar34 may now be removed in ar similar` manner and then thespring 21-` By areverse operation the springrand collar 34 are returned to theintermediate protector-rod section, the couplingsleeve 2| to the rightagain placed thereon, after which `the'intermediate protector-rodsection I1 isbroughtinto alignment withv the right end protector-rodsection I6 and the right couplingsleeve again clamped to these parts bymanipulation of the set screws 22 and 23. ate protector-rod* section issomewhat resilient and maybe ilexedforveiecting these operations andthereis some playin the vbearing 35|..y

It is to be understood that the form of my inv vention herewith shownand .described is to be taken as` a preferredexample of the same andthatvarious changes in the shape, size, and arrangement of parts may beresorted `'to without departing from the spirit of my invention `or then scope ofthe subjoined claims.
